5. Go camping
Who can forget those great camping trips that you used to do with your parents when you were just kids? Well, how about recreating those memories with your best friend now. You can go camping to some nearby hills or forest areas, or you could simply revisit those old memories by camping at the very same spots that you went as children. Doing it with your friend will not only help you to relive those memories, but you can create some exciting new ones as well.
